Using IVI with Visual C# and Visual Basic

•

Imports Agilent.Agilent34401.Interop

Module Module1

Sub Main()

Dim dmm As New Agilent34401

dmm.Initialize("GPIB::23", False, True,

"simulate=true")

dmm.Function =

Agilent34401FunctionEnum.Agilent34401FunctionDCVolts

dmm.DCVoltage.Configure(1.5, 0.001)

dmm.Trigger.Delay = 0.01

Dim reading As New Double

reading = dmm.Measurement.Read(1000)

dmm.Close()

Console.WriteLine(“The reading is {0}”, reading)

Console.ReadLine()

End Sub

End Module

The main differences include the following:

•

To use Visual Basic, select Visual Basic in Project Types.

•

To enforce type checking, insert a line at the start of the code. Type

Option Explicit On

•

To call the DCVolts function you need to insert a line of code. Type

dmm.Function =

Agilent34401FunctionEnum.Agilent34401FunctionDCVolts

•

To dimension a variable for the instrument and reading, use

Dim dmm

and

Dim

reading
